2.2.4.1. Bus Connectors
The rear panel of the SIM-3088 line switcher includes two multi-pin bus connectors. These
dedicated connectors are used to connect the switcher to the SIM-3022 analyzer and to
daisy chain other SIM-3088 line switchers.
The multi-pin bus connectors and bus cables carry several electrical connections between
the switchers and the analyzer. These buses include audio signals, control signals and power.
NOTE: Although the bus connectors and cables are the same, the signals are
different for the line-level switcher and for the microphone switcher and they
have dedicated connectors on the rear panel of the analyzer.
CAUTION: Always use the bus connector on the rear panel to connect SIM-
3088 line-level switchers to a SIM-3022 analyzer or to other SIM-3088 line
switchers only. Do not connect SIM-3081 microphone switchers to this connector.
CAUTION: Do not connect more than three switchers to a SIM-3022 audio
analyzer to avoid damaging the power supply. If more switchers are needed,
the SIM-3004 remote power supply is available from Meyer Sound.
